| 2025-02-08 10:38:00 +0100 | <tomsmeding> | I want an exception effect system so that I can statically determine whether an IO operation can throw |

| 2025-02-08 10:37:25 +0100 | <tomsmeding> | never mind the leagues of other partial functions in not-Prelude that don't have an x-partial warning |

| 2025-02-08 10:37:05 +0100 | <tomsmeding> | you could even defend this sizeOfListElt as "I'm only turning off the partiality warning in this separate file, so I have to watch out more here, but there's little code so it's easy to audit" |

| 2025-02-08 10:35:58 +0100 | <peutri> | mmm good point actually |
| 2025-02-08 10:35:55 +0100 | <tomsmeding> | put `sizeOfListElt :: [a] -> Int ; sizeOfListElt = sizeOf . head` in a file with -Wno-x-partial? |
| 2025-02-08 10:35:50 +0100 | <peutri> | oh sorry misread |
| 2025-02-08 10:35:11 +0100 | <peutri> | no, but it's a big file |
| 2025-02-08 10:35:02 +0100 | <tomsmeding> | in what situation is this warning going to help you? |
| 2025-02-08 10:34:46 +0100 | <peutri> | I want localized warning shunning :'( |
| 2025-02-08 10:34:33 +0100 | <tomsmeding> | and probably add -Wno-x-partial (or what was it) to the cabal file |
| 2025-02-08 10:34:30 +0100 | <peutri> | “function” overload. That's 1) functionality 2) signature match |
| 2025-02-08 10:34:24 +0100 | <tomsmeding> | I would accept your sizeOf (head) code in code review :p |
| 2025-02-08 10:33:49 +0100 | <peutri> | I mean, I'm not using it for the function at all, it's just the only [a]->a function I could think of |

| 2025-02-08 10:33:19 +0100 | <tomsmeding> | if you don't know 'head' is partial, you should think about what it does :p |
| 2025-02-08 10:32:46 +0100 | tomsmeding | personally feels that this head-is-partial warning is not helpful -- indeed, head is partial, but the programmer knows that, and the sign that something is off (or to be manually checked) is right there in the code: "head" |
| 2025-02-08 10:31:18 +0100 | <tomsmeding> | and retain the connection between the list elements and the sizeOf call that your head code had, but the undefined code lost |
| 2025-02-08 10:30:59 +0100 | <tomsmeding> | now you can pass in your list directly to this sizeOf' |
| 2025-02-08 10:30:53 +0100 | <tomsmeding> | note the P -> p |
| 2025-02-08 10:30:50 +0100 | <tomsmeding> | sizeOf' :: forall a. proxy a -> Int ; sizeOf' _ = sizeOf (Prelude.undefined :: a) |
| 2025-02-08 10:30:45 +0100 | <tomsmeding> | ooh |
| 2025-02-08 10:30:45 +0100 | <peutri> | oh your thing too |
| 2025-02-08 10:30:32 +0100 | <peutri> | I think I'm going to end up defining some term proxy alias in the end |
| 2025-02-08 10:30:21 +0100 | <tomsmeding> | sizeOf' :: forall a. Proxy a -> Int ; sizeOf' _ = sizeOf (Prelude.undefined :: a) |
| 2025-02-08 10:30:07 +0100 | <peutri> | in a “You have undefineds remaining in your code” kind of way |
| 2025-02-08 10:29:51 +0100 | <peutri> | but I can use Prelude's I guess |
| 2025-02-08 10:29:42 +0100 | <tomsmeding> | in what way? |
| 2025-02-08 10:29:39 +0100 | <peutri> | “but then Relude yells at me” |
| 2025-02-08 10:29:33 +0100 | <tomsmeding> | (for the right a, that is) |
| 2025-02-08 10:29:26 +0100 | <tomsmeding> | undefined :: a |
| 2025-02-08 10:29:22 +0100 | <peutri> | any common solution out there? |
| 2025-02-08 10:29:16 +0100 | <peutri> | yup |
| 2025-02-08 10:29:12 +0100 | <tomsmeding> | peutri: you're running into the unfortunate design of sizeOf |
| 2025-02-08 10:28:55 +0100 | <peutri> | I could put some (undefined :: a), but then Relude yells at me |
